The pictures thing is such an uphill battle. People take pictures of kids and post them on FB like it's okay. If my keds wanted to do any activity (eg, soccer) then parents would be taking pictures and posting them. It gets really annoying.

Yes, its an impossible battle. Even with all I've done, even relatives take pictures of my kids with snapchat. But I refrain from going nuts and accept reality. I will, however, take the steps that are within my realm of control.
In the end, as a low threat model individual, my approach to privacy is, I wont be invisible, but I can at least not be easy to find.
